I let my bike sit for nearly two years, unsurprisingly the fuel pump hoses and screens disintegrated with the local ethenol content. I just replaced the pump, filter, screen, and added submersible e-85 hose and a new battery. Turn the key and the pump runs for 2 seconds, engine turns over, but no start. If you trickle gas into the throttle body, it cranks until the gas is gone. The fuel line disconnected at the TB has a trickle for the "prime". Are injectors the next possible culprit, or is there another regulator up top? Thanks in advance.

There is no another regulator up top.

You could try cleaning them, i simply hooked up a hose and sprayed injector cleaner while cranking the engine over, using the pressure of the can to feed cleaner through the injectors. Make sure you disconnect the fuel pump.

You don't even need to crank the engine over if you have Bluetooth Buell dongle. There is a function in ECM Droid to cycle injectors.

Did you replace the fuel pressure regulator during the pump rebuild?
